This study demonstrates that both fully virtual and virtual reality (VR) integrated into real-world training programs are appropriate for use in the domain of welding training, depending on the level of task difficulty. Performance differences were virtually indistinguishable between participants in the fully virtual and the integrated training group at the low and medium weld difficulty levels. At the highest level of difficulty, it became apparent that the VR system was no longer solely sufficient for training. This study also tracked the usage patterns for the visual aids used in the VR simulator. These optional aids were presented to the users as overlays near the image of the weld as it was formed. Patterns observed suggest that the proper selection of certain overlays at certain stages during training was an indicator of success in both groups.
